| 摘 要： | 以柴达木盆地北缘某钻井中侏罗统的层序地层划分为例,对各种一维连续小波在地层划分中的效果进行尝试,发现采用db5小波用于层序划分较为理想。通过利用db5小波对自然伽马测井数据进行连续小波变换,将测井信号与深度的关系转换为与深度及尺度域的变化关系,以此识别出了层序界面。利用该小波变换进行的层序地层划分,与传统方法划分的结果基本一致。

| Abstract: | To take a borehole sequence stratigraphic division of Middle Jurassic Series in north margin of Qaidam Basin as an example, have tried various linear dimension continuous wavelet stratigraphic division effects, found that the db5 wavelet is ideal in the division. Through the use of db5 wavelet gamma-ray well logging data continuous wavelet transform, conversed the relations between logging signal and depth into varying relations between depth and scale domain, with the result that the sequential boundaries have identified. The division result from wavelet transform is basically the same with traditional method. |
